Industrial Silicone Masking Plugs and Silicone Caps

One of our specialties is silicone masking plugs and silicone masking caps. The team at Rubber Industries has been part of the manufacturing sector for close to half a century. If you're looking for professionals who can provide you with guidance that relates to custom rubber molded parts, plastic bonding, rubber-to-metal, liquid injection molding, liquid silicone rubber, transfer and compression molding and more, the Rubber Industries, Inc team can help you out at any time.

Silicone is one of the largest segments of our business. Rubber Industries supplies customers with industrial silicone masking caps and plugs that are both resilient and tough.

​Masking products allow protection of masking threads, weld nuts, threaded holes, dual flanged pull plugs while allowing a tight seal in these process environments. Using silicone or high temperature modified silicone will contribute to all the protection possible for threaded plugs with silicone caps or EPDM caps (for example).

​Rubber Industries, Inc has all the silicone masking plugs and caps needed to protect ports, threads and more by custom manufacturing exactly to your process masking needs. Silicone rubber and EPDM are both excellent options and can be used in painting, coating, and powder coating and finishing processes, while EPDM can be an excellent choice when chemical resistance is needed as a material for plating operations.

It is important to have flexible materials with excellent rebound and/or compression set in addition to chemical resistance. Silicone rubber and EPDM rubber meet the needs of flexibility as well as providing excellent protection of fittings, threads, tubing, sinks, holes, etc.

Silicone masking caps and plugs can withstand repeated temperature use of 350F - 600F depending on how we formulate the silicone rubber. EPDM masking caps and plugs tolerate temperatures up to approximately 300F - 450F.
